Sorry for the poor quality translation from Russian to English.
For the graphics card PCI-E Gigabyte AMD Radeon HD7970 3072MB 384bit GDDR5 [GV-R797OC-3GD] connected four monitors , three of which are native resolution of 2560 * 1440 Technology MST ( two mDp 1.2 - two on one port , and the third on the second ) .
Quite worn out with the Catalyst Control Center ver. 2013.0830.1943.33589 . Also try the latest beta version of amd_catalyst_13.11_betav9.2. - Observe the following problems .
1. Monitors can be connected to a maximum of 6 pieces ( four for mDP and two for HDMI and DVI). In this case, the resolution will be different . That is, 6 will not be able to use the technology Eytfinity monitors at the same maximum native resolution. Have to buy a second card , but with the work described below glitches turn into sheer torture associated with the infinite drag transfer monitors and finding lost windows.
2 . When you click on the tab " Diagnosis DisplayPort" Catalyst Control Center is cut down tightly , so even a reboot or reinstall does not help. Only helps restore the image of the system drive.
3 . When using HydraVision 13.9 to the grid nothing is fixed , - examined all of the instructions on the words very well, but in reality - is not working. The grid can be seen , but the windows do not attach .
When using the "Settings" :
1. Constantly monitors are mixed . For example the main monitor I have a third , and after the switch installed, it is the second , and it must constantly drag . In addition, the sequence is broken into the ranks - there are gaps between the monitors in the series, and therefore impossible to move to another monitor - the cursor does not move and can not do anything. That is, even you can not change the setting , or change the monitor , as the cursor is moved to the active window (which houses the Catalyst Control Center).
2 . When placing the fourth monitor bottom or top ( three screens are in a horizontal line) , and a fourth top or bottom , there is some irregularities in the displayed applications, such as the browser pane torn apart at one of three (in one series) monitors. When all four in a row , the applications are displayed normally .
3 . Constantly hiding applications and their windows , and some impossible to find even Alt + Spacebar . For example now I can not find a calculator that can be seen in the taskbar , but it can not be displayed .
4 . If you change the settings sometimes takes Catalyst Control Center, helps only a reboot.
The impression is that developers and monitors poorly tested products . It is clear , such monitors ( higher resolution and displey ports ) are not cheap , and probably lacks the capacity for a full test .
Not sure where to even apply for multimonitor problems and to signal?
